A3941KLPTR-T 编带

The is a full bridge MOSFET driver in 28 pin TSSOP package. This is a full bridge controller for use with external N channel power MOSFETs. A unique charge pump regulator provides full gate drive greater than 10V for battery voltages down to 7V and allows the A3941 to operate with reduced gate drive down to 5.5V. A bootstrap capacitor is used to provide above battery supply voltage required for N channel MOSFETs. An internal charge pump for high side drive allows DC 100% duty cycle operation. Integrated diagnostics provide indication of undervoltage, overtemperature, power bridge faults and can be configured to protect power MOSFETs under most short circuit conditions.
